Answer:
103.3 g
Explanation:
Data Given:
Volume of carbon tetrachloride (v) = 65.0 mL
Density of carbon tetrachloride (d) = 1.59 g/cm³
Solution:
Convert volume of carbon tetrachloride from ml to cm³
1 ml = 1 cm³
so,
65.0 mL = 65.0 cm³
Formula used to calculated mass of carbon tetrachloride should be taken for experiment.
d = m/v
Rearrange the above equation:
m = d x v . . . . . . .(1)
Put values in equation 1
m = 1.59 g/cm³ x 65.0 cm³
m = 103.3 g
Answer:
we should first calculate the no. of moles to find molarity
The balanced equation would be:
2HCl + Mg(HCO3)2 —> MgCl2 + 2CO2 + 2H2O
