How many O atoms are there in 51.4g CaSO4 [Solved]

>
51.4g = 136
X g = 64

So, there are 2.210^23 atoms of O in 51.4g CaSO4.

51.4g = CaSO4
51.4g = [40 32 (164) ]
51.4g = 136

X g = O
X g = ( 164 )
X g = 64

>
51.4g = 136
X g = 64

X g = 64 x 51.4g / 136
X g = 3289.6 / 136
X g = 24.18823529 > 24.2 g

Hope it helped :]

mole = 24.2 g/ 64
mole = 0.378125 > 0.378 mol

0.378 mol = no. of particles / ( 6.0210^23)
no. of particles = ( 6.0210^23) x 0.378 mol
no. of particles = 2.210^23

Hope it helped :]

0.378 mol = no. of particles / ( 6.0210^23)
no. of particles = ( 6.0210^23) x 0.378 mol
no. of particles = 2.210^23

Hope it helped :]

So, there are 2.210^23 atoms of O in 51.4g CaSO4.
