Answer:
The solubility of the salt is
46.75g salt/100g of H2O
Explanation:
If 7.70g of water can dissolve 3.60g at 21°C
That is 1.0g of water can dissolve (3.6÷7.7) grams of salt, that is 0.4675_g of salt at 21°C or 100 grams of water can dissolve 100×0.4675 = 46.75g
The solubility of the salt is
46.75g salt/100g of H2O

I gave the opportunity to help you for now on
16 grams.
Looking at the reaction equation, it's evident that for each mole of HBr
consumed, 1 mole of CO2 will be produced. So let's calculate the molar mass
of HBr and CO2 first.
Atomic weight hydrogen = 1.00794
Atomic weight bromine = 79.904
Atomic weight carbon = 12.0107
Atomic weight oxygen = 15.999
Molar mass HBr = 1.00794 + 79.904 = 80.91194 g/mol
Molar mass CO2 = 12.0107 + 2*15.999 = 44.0087 g/mol
Moles HBr = 30 g / 80.91194 g/mol = 0.370773461 mol
Grams CO2 = 0.370773461 mol * 44.0087 g/mol = 16.317258 g
Rounding to 2 significant digits gives 16 grams.
