Answer:
how many moles are in 400 g mgO with solutions?
[tex]{\boxed{Answer/Solution:}}[/tex]
[tex]\leadsto[/tex] Calculate the molar mass of MgO.
molar mass = (24.31 g/mol × 1) + (16.00 g/mol × 1)
molar mass = 40.31 g/mol
[tex]\leadsto[/tex] Calculate the number of moles of MgO.
Moles of MgO=400gMhO× [tex]\frac{1 mol mgO}{40.31g mgO}[/tex]
moles of MgO = 9.93 mol
