Help with these 4 chemistry mole questions?

Q: 1. What is the mass of 1.75 moles of zinc atoms?2. how many atoms are there in 1.50 moles of carbon?3. how many moles of atoms are there in 7.50 x 10^21 atoms of iron?4. what is the mass of 8.55 x 10^-3 mole of silver?if you can, please explain how you got the answer. thanks

A: Use this very basic chemistry equation:Number of Moles = (Mass of atoms) x (Molecular Mass)and this:Moles = 6.023×10^23 atoms (Avogadros number)Q1: Number of Moles = (Mass of atoms) x (Molecular Mass)therefore;(Mass of atoms) (m) = (Number of Moles) (n)/ (Molecular Mass) (M)m = n / Mm = 1.75 moles (n) / 63.55(??) (molecular mass of Zn)Q2: number of atoms = 1.50 x 6.02×10^23 (avogadros number)Q3: number of moles = 7.50×10^21 / 6.02 x 10 ^ 23Q4: mass = moles / molecular massm = n / Mm = 8.55×10^-3 / (molecular mass of silver) i think its 107I could give you the answers but then you wouldnt learn 😛

How do I find how many moles of hydrogen atoms…?

Q: 1: How many moles of hydrogen atoms are there in:a) 1.60 moles of zinc hydroxideb) 0.20 moles of sodium hydrogenphosphate-12-waterAlso, how do I find the mass of the following samples?a) 2.65 moles of phosphoric acid, H3PO4b) 0.0080 moles of mercury (II) iodidec) 1.60 moles of yellow phosphorous, P4Please help me. Thankyou.c) 0.350 moles of ammonium hydrogensulfateNote: How do I do this…please explain it all to me and show working so that I know how to do these. Do I need to know the formula for these 1st question ones? Please help me.1. c) 0.350 moles of ammonium hydrogensulfate(I forgot to type it in to the 1st question)…is 1. a)=3.2 moles of H atoms?Cattbarf, the example I am given with the answer is: How many moles of oxygen atoms are ther in 2.5 moles of glucose (C6H12O6)=6* moles of glucose=6*2.5=15 moles of oxygen atoms.This leads me to believe that number 1. a)=3.2 moles of H atoms not 1.6 as you have stated. Please justify your 1st answer. Thankyou.They are wanting H atoms not molecules which are obviously diatomic! Look at the example I put with the correct answer in the added details area. Oxygen is also present in the atmosphere as a diatomic molecule. Look at the example and answer. That is correct by the way.

A: moles=grams/atomic massatomic mass of H is about 1 so one gram equals one mole. Thats only for H though

molarmass/mass/atoms/moles questions.?

Q: How many moles are equal to 1.174E+23 atoms of calcium?What is the mass of 2.236E+25 atoms of sodium?What is the mass of 2.951E+23 atoms of iridium?How many atoms are in 31.420 g of zinc?How many atoms are in 0.817 mole of scandium?

A: 1. 1.174E+23/6.022E+23 = .19495 mol2. (2.236E+25/6.022E+23) 23.0g/mol = 854g3. (2.951.E+23/6.022E+23)192.2g/mol = 94.2g4. 31.420g/65.4g/mol = .4804 mol of Zn (.4804 mol Zn)(6.022E+23 atoms/mol) = 2.89 x 10^23 atoms5. .817mol(6.022E+23atoms/mol) = 4.92 x 10^23 atoms
