How many atoms of oxygen are in 8.43 g of magnesium sulfate heptahydrate (epsom salts)? how many atoms of oxygen are in 8.43 g of magnesium sulfate heptahydrate (epsom salts)?

The number of oxygen atoms in given amount of magnesium sulfate heptahydrate is

Explanation:

To calculate the number of moles, we use the equation:

Given mass of magnesium sulfate heptahydrate = 8.43 g

Molar mass of magnesium sulfate heptahydrate = 246.47 g/mol

Putting values in above equation, we get:

The chemical formula of magnesium sulfate heptahydrate is

1 mole of magnesium sulfate heptahydrate contains 1 mole of magnesium atoms, 1 mole of sulfur atoms, 11 moles of oxygen atoms and 14 moles of hydrogen atoms

According to mole concept:

1 mole of a compound contains number of particles

So, 0.0342 moles of magnesium sulfate heptahydrate will contain = number of oxygen atoms

Hence, the number of oxygen atoms in given amount of magnesium sulfate heptahydrate is

just did the assignment and the answer was #1 +2 n

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
