10. The density of olive oil has an accepted value of 0.936 g/mL. A student places an empty graduated cylinder on each of two different lab balances and sets the balances to read zero. She pours 100mL of oil in each graduated cylinder and measures the mass three times. Balance 1 reads 94.3 grams, 94.1 grams and 94.4 grams. Balance 2 reads 93.2 grams. 93.9 grams and 92.8 grams. Which statement best explains the accuracy and precision of both balances?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
