Question

calculate the mass of 0.5 mole of sugar C12 h22 o11 atomic of C is equal to 12 is equal to 12 is equal to 16​

Answer 1

Answer:

here is your answer

Explanation:

The Mass of C = 12u mass of H = 1u mass of O = 16u

amu of sugar =( 12×12) + (1×22)+ (16×11)

=144 + 22 + 176 = 342u

molar mass = 342 gram

mass = no. of moles × molar mass = 0.5 × 342 = 171 gram

Answer 2

The gram molecular mass of C₁₂H₂₂O₁₁ is

(12x12) + (22x1) + (11x16) = 144+22+176 = 342 grams

NOTE:

It is a known fact that 1 mole of any substance weighs as much as its Molecular weight.

For example, the gram molecular mass of Methane (CH₄) is 16 grams. It means when you take 16 grams of Methane, it is termed as 1 mole.

Now, We know 1 mole of sugar weighs 342 grams

So, 0.5 moles of sugar weighs 0.5 x 342 = 171 grams

Hope it helps!
