if 600.0 grams HF reacts with excess SiO2, how many grams of H2O are produced? Use the following molar masses: HF= 20.01g H2O=18.02g
Show work.

The mass of water produced is 180.02 g

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

......(1)

Given mass of HF = 600.0 g

Molar mass of HF = 20.01 g/mol

Plugging values in equation 1:

The given chemical equation follows:

By the stoichiometry of the reaction:

If 6 moles of HF produces 2 moles of water

So, 29.98 moles of HF will produce = of water

Molar mass of water = 18.02 g/mol

Plugging values in equation 1:

Hence, the mass of water produced is 180.02 g

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
