Answer:
The answer to your question is the mass of solute = 53.5 g
Explanation:
Data
mass of solution = 482 g
mass of solute = ?
mass percent = 11.1 %
Mass percent is a unit of concentration. It measures the mass of the solute divided by the total mass of the solution
Process
1.- Write the formula
Mass percent = mass of solute / mass of solution x 100
-Solve for mass of solute
mass of solute = Mass percent x mass of solution / 100
2.- Substitution
mass of solute = 11.1 x 482 / 100
3.- Simplification
mass of solute = 5350.2 / 100
4.- Result
mass of solute = 53.5g
A matter in the solid phase has a fixed shape and volume.
Answer:
23dm
Explanation:
so you have to do 10g +13dm so the you have to times it by 3 three times
From the information we have, this block of brown sugar has a volume of 8cm3
The mass of the block is 12. 9 grams.
We need to find out the density of the sugar.
For a solid material the formula for calculating density is given as:
Density = mass / volume
Therefore we simply fit in the above given values into this formula, so:
Density = 12.9 / 8
Density = 1.61
Therefore the density of the block of sugar is 1.61g/ml
Answer:
D. 34.5g
Explanation:
Using the following formula to calculate the mass of 1.5moles of sodium (Na);
Mole = mass/molar mass
Molar mass of Na = 23g/mol
mass = mole × molar mass
Mass of Na = 1.5mol × 23g/mol
Mass of Na = 34.5g
