Answer the questions below, using LT ( for is less than ), GT ( for is greater than ), EQ ( for is equal to ), or MI ( for more information required ) in the blanks provided. (a) The mass (to three significant figures) of 6.022 × 10 23 atoms of Na 23.0 g. (b) Boron has two isotopes, B-10 (10.01 amu) and B-11 (11.01 amu). The abundance of B-10 the abundance of B-11. (c) If S-32 were assigned as the standard for expressing relative atomic masses and assigned an atomic mass of 10.00 amu, the atomic mass for H would be 1.00 amu. (d) When phosphine gas, PH 3 , is burned in oxygen, tetraphosphorus decaoxide and steam are formed. In the balanced equation (using smallest whole-number coefficients) for the reaction, the sum of the coefficients on the reactant side is 7. (e) The mass (in grams) of one mole of bromine molecules is 79.90.

Solution Summary: The author explains that the atomic mass of an element will depend on the masses of its isotopes and their natural abundance.

atoms of Na 23.0 g.
(b) Boron has two isotopes, B-10 (10.01 amu) and B-11 (11.01 amu). The abundance of B-10 the abundance of B-11.
(c) If S-32 were assigned as the standard for expressing relative atomic masses and assigned an atomic mass of 10.00 amu, the atomic mass for H would be 1.00 amu.
(d) When phosphine gas, PH3, is burned in oxygen, tetraphosphorus decaoxide and steam are formed. In the balanced equation (using smallest whole-number coefficients) for the reaction, the sum of the coefficients on the reactant side is 7.
(e) The mass (in grams) of one mole of bromine molecules is 79.90.
When Kay added 30g of Hydrochloric acid (HCI) to 65g of Zn, bubbles appeared and a white precipitate, zinc chloride (ZnCl2) was produced. She found that the mass of the zinc chloride was 93g. Since the law of conservation of matter stated that matter can’t be created or destroyed, she was puzzled about the difference in mass. What is the best explanation for the missing 2g?
why at the end do you write mass of O2, but then didn't do 32g as the multiplier?
What is the molecular weight of sugar, C6H12O6 in atomic mass units?
And If you had one mole of sugar molecules, how much would it weigh?
