an irregularly shaped piece of metal of density 7.80 g/cm^3 weighs 429g when completely immersed nitrobenzene,which has a density of 1.2 g/cm^3. find the volume of piece of metal

Wouldn't you multiply the RD by 1000 kg/m^3 to get density?

A basketball is pressurized to a gauge pressure of PG = 55 kPa when at the surface of a swimming pool. (Patm = 101 kPa). The ball is then submerged in the pool of water which has a density ρ = 1000 kg/m3. Assume the ball does not change in mass, temperature, or volume as it is submerged. Calculate the absolute pressure inside the basketball in kPa when it is at the surface.  Write an equation for the pressure difference ΔP between the inside and outside of the ball when it is submerged a distance y below the surface of the water.  Solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. At this depth the pressure inside the basketball is the same as the pressure outside the ball.

Two large tanks, each holding 100L of liquid, are interconnected by pipes, with the liquid flowing from tank A into tank B at a rate of 3L/min and from B into A at a rate of 1L/min. The liquid inside each tank is kept well stirred. A brine solution with a concentration of 0.1kg/L of salt flows into tank A at a rate of 6L/min. The (diluted) solution flows out of the system from tank A at 4L/min and from tank B at 2L/min. If initially, tank A contains pure water and tank B contains 10kg of salt, determine the mass of salt in each tank at time t≥0. What is the solution to the system? x(t)=                                     y(t)=

A chamber is filled with a gas that has a pressure of 0.250 atm and ???is connected to a mercury-filled u-tube with a width of 0.01m. The left side of the tube is closed and there is a vacuum at the top of the tube. How much higher is the mercury on the left-hand side compared to the right-hand side?

A simple thermometer is formed by taking a large spherical container of volume 1.13m³ and filling it with an ideal gas. Then, a U-shaped tube is attached that is very narrow so that very little fluid/gas can fit inside the tube. The tube has a small quantity of a fluid of density 1200kg/m³ placed in it. In equilibrium at room temperature - 21.9°C - the height of the fluid on both sides of the U-shaped tube are level. This is illustrated in the image below. What is the temperature of the gas in the spherical container when the left side of the fluid is 13.25cm higher than the right side of the fluid in the U-shaped tube? Atmospheric pressure is 101000Pa. °C

There is a liquid mixture at 20 ° C of 40% acetic acid and 60% by mass of water. Calculate the density of the mixture

A 5.50 L sample of neon at 6.67 atm is added to a 10.0 L cylinder that contains argon. If the pressure in the cylinder is 7.63 atm after the neon is added, what was the original pressure (in atm) of argon in the cylinder? Hint is given in the feedback. Answer: 6.3315 Hint, what pressure would the neon have in the second container if no argon were present?
