Document Summary
Calcium is the most abundant metal in your body ~ 30 moles. = 30 mol (6. 022 x 1023/1 mol ca) In (a) the number of atoms are < naso we must have less than one mole. In (b) we have 30 moles therefore we must have more atoms than na. Homework **midterm #1: determine the number of water molecules as well as the number of hydrogen and oxygen atoms in 3. 26 g of water, determine the mass of 7. 92 x 1019 moles of carbon dioxide molecules. Molar mass of: c (12. 01, h (1. 01, n (14. 01, o (16. 00) Gas constant: 8. 314 j/k mol (most likely will only need this one, 0. 08206 l atm/k mol. R is the gas constant units will depend on units in which p and v are given. 8. 314 j/k mol (most likely will only need this one) or 0. 08206 l atm/k mol. Pressure of a fixed amount of gas at constant temperature is inversely proportional to volume.
