4 g of X2O3, an oxide of efement X, contains 2.8 g of X. How many moles of X<br> are there?
ziro4ka [17]

Moles of X are 0.925 moles.

A mole is a totally vital unit of dimension that chemists use.The mole, symbol mol, is the unit of amount of substance inside the worldwide device of gadgets. the amount quantity of the substance is a measure of how many simple entities of a given substance are in an item or sample. The mole is described as containing exactly 6.02214076×10²³ primary entities

mass  of X2O3 = 4 g

so moles = mass/molar mass

molar mass  of X2O3 =  2*X + 48 -

Given, that the mass of X = 2.8g

        mass of O = 4 - 2.8 = 1.2g

A mole of O = 1.2g/16 = 0.075 mole

∴ mole of X = 1 - 0.075 = 0.925 moles.

Milk has a density of 1.04 g/ml. If you have a volume of 510 ml, what is the mass in grams
Law Incorporation [45]

Density is defined as the ratio of mass and volume. The formula of density is:

density = \frac{mass}{volume}     -(1)

Density of milk = 1.04 g/mL   (given)

Volume of milk = 510 mL      (given)

Substituting the values in formula (1):

1.04 g/mL = \frac{mass}{510 mL}

mass= 1.04 g/mL \times 510 mL

mass = 530.4 g

Hence, the mass of the milk is 530.4 g.
