Determine moles of 1.5g of sodium carbonate.

KIM [24]

Answer:

0.014mol

Explanation:

Given parameters:

Mass of Na₂CO₃ = 1.5g

Unknown:

Number of moles = ?

Solution:

Number of moles of a compound is mathematically expressed as;

Number of moles = $\frac{mass}{molar mass}$

Molar mass of Na₂CO₃ = 2(23) + 12 + 3(16) = 106g/mol

Number of moles = $\frac{1.5}{106}$ = 0.014mol

Calculates the equivalent mass of calcium chlorate CA (CI03) 2

love history [14]

Answer:

207g

Explanation:

Given compound:

Ca(ClO₃)₂

The equivalent mass can be derived by summing the molar masses of each atom

Molar mass of Ca = 40

Cl = 35.5

O = 16

Now solve;

Molar mass = 40 + 2(35.5 + 3(16)) = 207g
