How many atoms are there in 8.5 g of mg no3 2
WebJun 23, 2016 · Step 1 Avogadro's constant says that 1 mole of any atom contains 6.022 ⋅ 1023 atoms. In this case you have 3.40 ⋅ 1022 atoms: 3.40⋅ 1022 atoms 6.022 ⋅ 1023 atoms mol = 5.65 ⋅ 10−2mol Step 2 The atomic mass of helium (He) will give you the weight of one mole of this molecule: 1 mol = 4.00 gram: 4.00 g mol ⋅ 5.65 ⋅ 10−2mol = 0.226g WebStep 1: Enter the atomic mass number, grams and x in the respective input field Step 2: Now click the button “Calculate x” to get the output Step 3: Finally, the conversion from grams to atoms will be displayed in the output field How to Convert Grams to Atoms?

WebNumber of moles of Fe atoms = Atomic massMass = 55.85558.5=10. 558.5 g of Fe corresponds to 10 moles of Fe and has 10N A atoms of Fe. Option A - 12 g of carbon means Avogadro's number, therefore, 60 g of carbon means, 5 moles of carbon and thus contains 5×N A atoms, twice of this equals 10N A atoms. Option B - 10N A atoms. WebThis will give us zero 283 moles of magnesium percy 4.5 times 10 to the 22 atoms of copper 6.02 times 10 to the 23rd Adams of copper in one mole of copper. This would equal 0.075 moles of copper For D 382 grams of cobalt. We have 58.9 g of cobalt and one more. Give us 6.49 molds of Cobalts. E .055g of 10, 118.7 g of 10 in one mole of 10.
Web1 Answer. Figure 1: we have one $\ce {Mg}$, two $\ce {N}$ ( $2 \times 1$) and six $\ce {O}$ ( $2 \times 3$) in $\ce {Mg (NO3)2}$. Now all you need is to know that 1 mole equals … WebThe explanation for the correct option. One mole of Ammonia contains one GAM of ammonia, 17gm, given mass = 8.5g. 1 mole = 6.022 X 10 23 atoms ( 1mole contains 6.022 X 10 23 atoms) Thus option (B), is correct 8.5g of NH 3 contains 3.011 X 1023 atoms.
