Question

Convert 1.2 moles of NaCl (table salt) to grams.

Answer 1

70. g NaCl

Explanation:

For every one mole of a substance, there is a molar mass that coincides with the values of the periodic table. NaCl has a molar mass of 58.44g (Na+Cl). You then take this molar mass and multiple it by the number of moles asked (1.2) to find the grams present.

58.44g * 1.2mol = 70.128g

Then you would round to 2 sig figs to get 70. g of NaCl
