Answer:
SOURCE :https://socratic.org/questions/how-many-atoms-of-each-element-of-agno-3-are-in-0-15-mol-of-agno-3
Explanation:
- From 0.15mol of
AgNO3 , we can find the moles of each element by counting how many of each element is present in the entire compound. InAgNO3 , there's 1 Ag, 1 N and 3 O. - Then, we convert from moles of each element to the number of atoms using Avogadro's number
6.02x1023 .
I went ahead and set up the two steps above in 1 line for each element:
Ag atoms=0.15mol AgNO3⋅1mol Ag1mol AgNO3⋅6.02x1023Ag atoms1mol Ag=9.0x1022Ag atoms
=2.7x1023O atoms
