It’s 8 because you mulitiply 4x2 so if you had to do oxide(oxygen) it would be 4x7 cuss you multiply the number added before H2O7 and the small numbers already there (deside it) is multiplied

The molar mass of CO2 is 44.01 g/mol. Which is the mass of 3.21×1025 molecules of CO2
sineoko [7]

Given:

Molar mass of CO2 = 44.01g/mol

3.21x10^25 molecules of CO2

Required:

Mass of CO2

Solution:

Avogadro’s number states that for every mole of atom, there are 6.023x10^23 units of atom. The units may be formula units, atoms. In here, you need to divide 3.21x10^25 molecules of CO2 to 6.023x10^23 molecules per mole.

 

3.21x10^25 molecules of CO2 / 6.023x10^23 molecules per mole = 53.30 moles CO2

53.30 moles CO2 (44.01g/mol CO2) = 2346 g of CO2

Change 23 degrees Celsius to F
Fed [463]
Rewrite the formula C=5/9(F-32) substituting 23 for C: 23=5/9(F-32), then multiply both sides by the reciprocal of 5/9.
(9/5)*(23)=(9/5)*5/9(F-32)
41.4=F-32; add 32 to both sides.
41.4+32=F-32+32
73.4=F
