How many moles are in 30g of C12H22O11?
2 answers:
You first want to set up an equation like the one I did then you break down
C12H22O11 and find their molar masses C= (how ever many you have which is 12) x molar mass 12.011= 144.132
H = 22 x 1.008 = 22.176
O= 11 x 15.999 =175.989
And then you add 144.132 + 22.176 + 175.989= 342.297g (that’s your molar mass for C12H22O11 ) and then you want to divide it by the 30g you already have because you want to cancel out grams and get moles.

Answer:
4.67 kg
Explanation:
Given data
- Dimensions of the lead sheet: 75.0 cm by 55.0 cm by 0.10 cm
- Density of lead: 11.3 g/cm³
Step 1: Calculate the volume of the sheet
The volume of the sheet is equal to the product of its dimensions.
Step 2: Calculate the mass of the sheet
The density (ρ) is equal to the mass divided by the volume.
