Write the names of the following compounds and deduce their molar masses.
$N{a}_2{SO}_4,K_2{CO}_3,{CO}_2,{MgCl}_2,NaOH,{AlPO}_4,{NaHCO}_3$

$N{a}_{2}S{O}_4$ : Sodium sulphate

Molar Mass : $23\left(2\right)+32+16\left(4\right)$ = $46+32+64$ = $142$ g/mol

$K_{2}C{O}_3$ : Potassium carbonate

Molar Mass : $39\left(2\right)+12+16\left(3\right)$ = $78+12+48$ = $138$ g/mol

$C{O}_2$ : Carbon dioxide

Molar Mass : $12+16\left(2\right)$ = $12+32$ = $44$ g/mol

$MgC{l}_2$ : Magnesium chloride

Molar Mass : $24+35.5\left(2\right)$ = $95$ g/mol

$NaOH$ : Sodium hydroxide

Molar Mass : $23+16+1$ = $40$ g/mol

$AlP{O}_4$ : Aluminium phosphate

Molar Mass : $27+31+16\left(4\right)$ = $27+31+64$ = $122$ g/mol

$NaHC{O}_3$ : Sodium bicarbonate

Molar Mass : $23+1+12+16\left(3\right)$ = $23+1+12+48$ = $84$ g/mol
