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.

1. During an oceanic plate convergence, the plate will sink
Lorico [155]

Answer:

1. denser

2. subduction

3. divergence

4. hot spots

5. earthquakes

6. An underwater hot-spot volcano occasionally erupts, and the lava solidifies into an island. However, the plate that lies above the hot spot continues to move due to slab pull and ridge push, so the stationary volcano will be in a different location when it erupts again. This forms a new island, and the process may continue.

A chemist measures the amount of bromine liquid produced during an experiment. She finds that 496g of bromine liquid is produced
vfiekz [6]

Answer:

6.208 mol

Explanation:

Mass of Bromine Liquid = 496g

Number of moles = ?

Relationship between number of moles and mass is given as;

Number of moles = Mass / Molar mass

Molar mass of Bromine = 79.9g

Number of moles = 496 / 79.9 = 6.208 mol
