Question

37 gr Ca (OH) 0,5 mol bo'lsa Mr toping​

Answer 1

Відповідь:

M(Ca(OH)2)=40+2*(1+16)=74g/mol

n(Ca(OH)2=37/74=0,5mol

Answer 2

Ca(OH)2 has a molar mass of 74.09 g/mol. To find the mass of 0.5 mol of Ca(OH)2, you can use the formula:

mass = moles x molar mass

So, mass = 0.5 mol x 74.09 g/mol = 37.045 g

Therefore, if you have 0.5 mol of Ca(OH)2, the mass of it would be 37.045 grams.
