Answer:
Sodium bicarbonate.
Explanation:
The gas produced during the mixing of bath bombs in water is Sodium bicarbonate. If the reaction is with citric acid then Sodium citrate can be produced. They are weak acid with bicarbonate base. These bath bombs can be a mixture of wet and dry substances and any shape can be mold.
1 mol of Silicon = 28.0855 g (in average)
then
1 mol = 6.022*10^23 atoms
then
28.0855/(6.022*10^23) g/atom
4.66381*10^-23 g per atom
Gases use Cubic Feet (cu.ft).
28,317 cc (cm³ or mL).
For liquids we have the US Gallon (gal).
1.0 US gal. = 3,785 cc (cm³ or mL).
0.0024 g of Ba(NO₃)₂
Explanation:
First we need to determine the molecular weight of barium nitrate Ba(NO₃)₂
molecular wight of Ba(NO₃)₂ = molecular weight of Ba × number of Ba atoms + molecular weight of N × number of N atoms + molecular weight of O × number of O atoms
molecular wight of Ba(NO₃)₂ = 137 × 1 + 14 × 2 + 16 × 6 = 261 g/mol
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Ba(NO₃)₂ = 0.625 / 261 = 0.0024 g
