How many moles of sodium are represented in sodium phosphate?
In one mole of compound, there are also 3⋅mol of sodium. Now you have quoted 7⋅Na3PO3 , i.e. 7⋅formula units OR 7⋅moles of sodium phosphate.
How many moles of sodium are in Na3PO4?
We do this by looking at the periodic table, which gives the molecular weight of every single element. The molecular weight tells you how many grams of that element makes up one mole of that element. In Na3PO4, there are 3 Na, 1 P, and 4 O. So the total molecular weight is 3(22.99) + 1(30.97) + 4(15.99) = 163.9 g/mol.
How many moles of 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 moles is sodium?
In grams, a mole is one formula mass. For example, 1 mol of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table).
How many moles of sodium are there in 2.97 moles of the following compounds?
Two moles of sodium. So two into 2.97. Okay. 22.97 equal to 5.97 moles of sodium.
How many moles of sodium ions are there in 1 mole of sodium carbonate?
For every 1 mole of CO3, we have 2 moles of Na. Using our moles of Na2CO3, we know we have 2*0.03774 mol of sodium from sodium carbonate.
How many phosphate ions are in Na3PO4?
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. Therefore, it will take three +1 sodium ions to balance the one -3 phosphate ion. This will make the formula for Sodium Phosphate Na3PO4 .
