Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of cork = 2.88 g
volume = 12 mL
The density is
We have the final answer as
0.24 g/mL

Answer:
11 moles
Explanation:
1 mole of C12H22O11 molecules produces 12 moles of CO2 molecules and 11 moles of H2O molecules.
Answer:
5.48 g
Explanation:
The concentration in M represents the mol/L, or the number of moles in each L of the solution, and it can be calculated by the number of moles (n) divided by the volume of the solution (V) in L, so:
M = n/V
1.71 = n/0.100
n = 0.171 mol
The molar mass of methanol is 32.04 g/mol, and it is the mass (m) divided by the number of moles:
FM = m/n
32.04 = m/0.171
m = 5.48 g
