Answer:
7.1 mL
Explanation:
Step 1: Given data
Moles of methyl benzoate (n): 0.057 mol
Molar mass of methyl benzoate (M): 136.15 g/mol
Density of methyl benzoate (ρ): 1.094 g/mL
Step 2: Calculate the mass corresponding to 0.057 moles of methyl benzoate
We will use the following expression.
m = n × M = 0.057 mol × 136.15 g/mol = 7.8 g
Step 3: Calculate the volume corresponding to 7.8 g of methyl benzoate
We will use the density formula.
ρ = m/V
V = m/ρ
V = 7.8 g/1.094 g/mL
V = 7.1 mL
There are several differences between a physical and chemical change in matter or substances. A physical change is a substance that doesn't change what the substance is, a chemical change on the other hand is when there is a chemical reaction, a new stubstabce is formed and energy is either given off or absorbed.
Hope this helps. :)
44 amu because oxygen has an atomic weight of 16, and 16 plus 16 is equal to 32, and the atomic mass of carbon is 12, and 32 plus 12 is 44.
