Answer:
8.20 % → Percent yield reaction
Explanation:
To find the percent yield of reaction we apply this:
(Produced yield / Theoretical yield) . 100 = %
Produced yield = 112.9 g
Theoretical yield = 1375.5 g
We replace → (112.9g / 1375.5 g) . 100
8.20 % → Percent yield reaction
Answer:
number of moles= 0.844 moles
Explanation:
Number of moles of Hydrogen atom = given mass / molar mass
given mass= 0.850 g
Molar mass= 1.007 g
number of moles= 0.850/1.007 = 0.844 moles
Answer:
Molality = 66.67g/L
Explanation:
Mass of sucrose = 100g
Volume of water = 1.50L
Molality = mass of substance/ volume in L
Molality = 100 / 1.50
Molality = 66.67g/L
Molality of 100g of sucrose in 1.50L of water is 66.67g/L
