## How many sodium ions are in Na2SO4?

Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 .

## How many moles of ions are in Na2SO4?

Referring to those numbers, the formula Na2SO4 means: two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).

**How many grams of sulphate ions are present in 0.5 mole of sulphate?**

The mass of sulfate ions present are 48 grams.

### How many sodium ions are in 2 moles of sodium phosphate?

a) 2 moles of sodium phosphate. ANSWER: 36.12 x 1023 Na ions, which isn’t in correct Scientific Notation OR Sig Figs, so,… = 4 x 1024 Na ions NOTE: your book includes 2 sig figs.

### How many ions are in sulfate?

It is important to note that sulfate is a polyatomic ion, and not a collection of five different ions. The Roman numeral “II” denotes the +2 oxidation state of iron. This allows it to bond with just one sulfate anion.

**How many atoms of Sulphur are in 0.5 mole of SO2?**

one mole of SO2 contain 6.023 into 10^ 23 molecules of SO2. then 0.5 mole of a SO2 contains 3.01 into 10 ^23 molecules of So2. hence 3.01*10^23 has multiply it by 3.

## How many molecules are there in 0.5 mol of CO2?

The number of molecules present in 0.5 moles of CO2 is6. 022 x 1023 x 0.5 = 3.011 x 1023.

## How many moles are in Na+?

So total moles of Na+ = 0.008×3=0.024moles(answer)

**How many phosphate ions are in sodium phosphate?**

two ions

Sodium Phosphate is an ionic compound formed by two ions, Sodium Na+ and Phosphate PO−34 . In order for these two polyatomic ions to bond the charges must be equal and opposite.

### How do you calculate the number of Na+ ions in Na2SO4?

Use the number of moles of sodium per mole of sodium sulfate. First, calculate the moles of sodium sulfate you have in a 14.2g sample. Now, for every 1 mol of N a2SO4 you have 2 moles of N a+ ions.

### What is the molarity of sulfate ions in N A2SO4?

Therefore, 1mol of N a2SO4 will give 1mol of SO2− 4 and thus, the molarity of sulfate ions will be equal to that of the sodium sulfate. M SO2− 4 = 0.150M M N a+ = 0.300M.

**How many sodium ions are there in a molecule of sodium sulphate?**

The sodium has a charge of +1. Therefore there are 2 sodium ions in a molecule of sodium sulphate. I calculated to 2 s.f. so that you can do the calculation yourself.

## How do you find the molar mass of sodium sulfate?

Find the molar mass of sodium sulfate. molar mass = atomic mass in grams. 2(23) + 32 + 4(16) = 142 grams per mole. Divide the mass of the sample by the molar mass to obtain moles.
