How many hydrogen atoms are in the compound (NH4)2CO3? Alex has a big black tattoo of a teddy bear on their back. Iron (II, III) oxide was used as the tattoo ink and has the chemical formula Fe3O4. What is the molar mass of iron (II, III) oxide? Alex’s mass before getting the tattoo was 61.5 kg. The tattoo contains 5.20x1023 molecules of iron (II, III) oxide. What is Alex’s mass (in kg) after getting the tattoo? JJ is making miso soup. 1 bowl of soup has a volume of 375 mL. The soup has 1.00 g of table salt in it (NaCl). What is the salt concentration of the soup in g/L? Express this as m/V%. How many molecules of NaCl are in one bowl of JJ’s miso soup?
