120 g calcium is equal to 3 moles.
3,50 moles of glucose is equal to 630,56 g.
The molar mass of glucose is 180,16 grams.180,16 g------------1 mol35 g------------------xX = 0,194 moles or 194 millimoles
0,0235 x 180,16 = 4,238 g
The answer is 0,4 moles.
2.,7 moles of glucose have 486,432 g.
120 g calcium is equal to 3 moles.
3,50 moles of glucose is equal to 630,56 g.
The molar mass of glucose is 180,16 grams.180,16 g------------1 mol35 g------------------xX = 0,194 moles or 194 millimoles
n = 817 g x (1 mol / 120 g) = 6.81 mol
C6H12O6 is the chemical formula of glucose (not sucrose !).The mass of 4.00 moles of glucose is 720,64 g.
0,0235 x 180,16 = 4,238 g
3,80 g Zn have 0,058 moles.
The formula is: number of moles = g Be/9,012.
Answer: 7 x 10-3 g glucoseProcess below:First convert 40 µmol to moles. 1 µmol = 1 x 106 mol.40 µmol x (1 mol)/(1 x 106µmol) = 4 x 10-5 molMultiply 4 x 10-5 mol by the molar mass of glucose (180.156 g/mol).4 x 10-5mol glucose x (180.156 g glucose)/(1 mol glucose) = 7 x 10-3 g glucose
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
The answer is 0,364 moles.
