Answer:
1.32*10^23 molecules
Explanation:
sucrose formula: C12H22O11
molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol
75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11
0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)
It already is a chemical equation just copy that exact thing
Answer:
The number by which we divide is called the divisor. The result obtained is called the quotient. The number left over is called the remainder.
Explanation:
the balanced equation for formation of potassium oxide is as follows
4K + O₂ --> 2K₂O
molar ratio of K to K₂O is 4:2
when 4 mol of potassium reacts, 2 mol of potassium oxide is formed
when 4 mol of K reacts - 2 mol of K₂O
when 1.52 mol of K reacts - 2/4 x 1.52 = 0.76 mol of K₂O
0.76 mol of K₂O is formed
