Answer: 24.2109 g
Explanation:
Hydrogen has a molar mass of 1.007947 g/mol so since hydrogen gas has 2 hydrogens, you can multiple this by 2 and then multiply that by 12.01 to get the total mass of 12.01 moles of hydrogen gas.
V=n/M
V=(6.34:125.55 g/mol)/0.72
V=0.07 L = 70 ml
Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.
<h3>Rate of reaction?</h3>
The term rate of reaction refers to how quickly or slowly a reaction proceeds. The surface area of solid reactants is an important factor that influences the rate of reactions when a solid reactant is involved.
Hence, Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.

The molarity of solution made by diluting 26.5ml of 6.0ml hno3 to a volume of 250ml is calculated using the following formula
M1V1 = M2V2, where
M1 = molality 1 (6.00m)
V1= volume 1 (26.5 ml)
M2 = molarity 2(?)
v2=volume 2 (250)
M2 = M1V1/V2
M2= 6 x26.5/250 = 0.636 M
