Answer:
2.2G
Explanation:
A. 0.1g atom of carbon – 0.1g atom approach 0.1 moles of the element, so 0.1g atom of the carbon approach there's 0.1 mole of carbon atom present.
The atomic mass of carbon is 12g consequently the mass of 0.1 moles of carbon is 1.2g
B. 0.1 mole of NH3 - To convert moles into mass, the given variety of moles is extended with the aid of using the molar mass of the molecule. So ammonia is fashioned with the aid of using a nitrogen atom and three hydrogen atoms so the molecular mass of NH3 is 17g.
The mass of 0.1 moles NH3will be 0.1×17=1.7g
C. 6.02×1022 mol of H2- Conversion of the variety of atoms to mass is performed with the aid of using multiplying the given variety of atoms to the molar mass after which dividing it with the aid of using the Avogadro variety.
The atomic mass of H2 is 2μ. The mass of 6.02×1022 mol of H2 might be 6.02×1022×26.023×1023=0.19g
D. 1120cc
of CO2 at STP- 1 mole of any fueloline is same to 22.4L
at STP
So the whole variety of the mole might be 112022400 (22.four L is transformed to mL)
Weight might be same to mol extended with the aid of using molecular weight 112022400×44=2.2g
