2xNa => 46u Atomic Mass
1x(SO4) => 96u atomic mass
tot = 142u
4.5g/142u = 0.03169014085g/u
Ans x 96u = 3.04g = 3.0g of SO4

What is the mass in grams of 0.150 mol of sodium sulfate?
Sodium Sulfate is Na2SO4 and the molecular weight is 142. So 0.15 moles would have a mass of 0.15 x142 = 21.3g.
Which information would be required to determine the mass number of nitrogen?
7protons and 7 neutrons
What measurements would you make to determine the average mass of a heaping microspatula of NaCl?
You would obtain a test tube, measure the mass of the test tube. Then add the NaCl to the test tube and measure the mass. Then subtract the mass of the test tube from the mass of the test tube+the NaCl to find the mass of the NaCl.
What is counted in an atom to determine mass number?
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.
How can you demonstrate that a piece of chalk has mass?
Put it on a balance and determine its mass.
What is the mass of Na2SO4 needed to make 2.5 L of 2.0 M solution?
how man molecules are there in 450 grams of Na2SO4. the simple formula to determine of mole is NO OF MOL= GIVEN MASS IN gm/MOL:MASS OF COMP: , AND IMOL = 6.02X1023 . SO, 19. 077X1023 molecules are present in 450 grams of Na2SO4.
How many moles are in Na2SO4?
just one. If you were given a mass of Na2SO4, then you could find the number of moles by dividing the mass by the molar mass(total of the mass of all elements from the mass on the periodic table). But Na2SO4 by itself is just one mole.
Mass of Na2SO4 that contains 3.011023 formula units?
This mass is 72,02 g.
How would you find the mass of a paper clip?
You would determine its mass using a mass balance.
What is the mass in grams of 0.150 mol of sodium sulfate?
Sodium Sulfate is Na2SO4 and the molecular weight is 142. So 0.15 moles would have a mass of 0.15 x142 = 21.3g.
What steps would you take to determine density of an egg?
You would first determine the mass of the egg. Then you would need to determine the volume of the egg through water displacement. Then you would need to divide its mass by its volume, and that will give you the density.
How many grams of sodium sulfate will be formed if you start with 200grams of sodium hydroxide and you have an excess of sulfuric acid?
First write down the BALANCED reaction equation. 2NaOH + H2SO4 = Na2SO4 + 2H2O Note the molar ratios are 2:1::1:2 So two moles of NaOH produces one mole of Na2SO4 Next calculate tghe moles of NaOH mol(NaOH) = 200/(23 + 16 + 1) = 200/40 = 5 mol(NaOH) = 5 (This figure is equivalent to '2' above) mol(Na2SO4) = 5/2 = 2.5 ( Equivalent to '1' above) mol(Na2SO4) ; 2.5 = mass(g) / (2 x 23) + 32 + (4 x 16)) 2.5 = mass(g) / 142) mass*Na2SO4) = 2.5 x 142 = 355 g
How would you determine the mass of a cup of water?
You would weigh it on your kitchen scale
How would you measure a pumpkin?
I would recomend measuring a pumpkin based on its mass, which can be found by weighing it (not that weight= mass, but weight can be used to determine mass as long as the pumpkin remains on Earth) You could also determine the volume by measuring how much water it displaces. I would stick to mass, though
When calculating the number of moles of solid Na2SO4 the factor used is?
The molar mass of anhydrous sodium sulfate is 142,04.
What deflects the ions?
In a mass spectrometer, the magnetic field is used to deflect ions.
Which two tools would help you determine the density of a block?
Something to determine volume (like a bucket of water or a ruler), and a balance to determine mass. Divide the mass of the block by its volume to find the density of the block.
