Answer:
Mass = 10.0 g
Explanation:
Given data:
Molarity = 1.50 M
Volume = 210 mL ( 0.21 L)
Grams of CH₃OH = ?
Solution:
Number of mole = molarity × volume
Number of mole = 1.50 M × 0.21 L
Number of mole = 0.315 mol
Mass of CH₃OH:
Mass = Number of moles × molar mass
Mass = 0.315 mol × 32.04 g/mol
Mass = 10.0 g
Answer:
it would be the second choice
Answer:
5010J
Explanation:
The following data were obtained from the question:
Mass (m) = 15g
Heat of fusion (ΔHf) = 334J/g
Heat required (Q) =..?
The heat energy required to melt the ice can be obtained as follow:
Q = m·ΔHf
Q = 15 x 334
Q = 5010J
Therefore, the heat energy required to melt the ice is 5010J.
