Question

which of the following is true about 1.7g NH3 and 1.8g H20

a) Both contains same number of electrons
b)Both contains same number of protons
c)Both of them contains same number of molecules
d)All are correct​

Answer 1

Answer:

d)All are correct (IDK)

Explanation:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities

Answer 2

Answer:

all r correct

Mass of CH4=12+4=16g

Given mass=1.6g

Number of moles=1.6/16=0.1

Number of atoms in 1 mole=6.022×10^23

Number of atoms in 10 moles=6.022×10^23×0.1=6.022×10^22

NOW NH3

Mass of NH3=14+3g=17g

Number of moles in 1.7g of NH3=1.7/17=0.1 moles

Number of atoms in given mass=6.022×10^23×0.1=6.022×10^22

Same for H2O,

Number of moles in given mass=1.8/18=0.1

Number of atoms in given mass=6.022×10^23×0.1=6.022×10^22

All the compounds have same number of atoms in the given mass.
