560g of silicon dioxide to molecules of silicon dioxide. SiO2?

Given :

560 gram of silicon dioxide.

To Find :

Number of moles of silicon dioxide in 560 gram.

Solution :

We know, molecular mass silicon dioxide is 60 gram/mol.

So, number of moles of silicon dioxide in 560 gram is :

Now, one mole of any compound contain .

So, number of molecules in 9.33 moles of silicon dioxide is :

Hence, this is the required solution.

answer; a male inherits only one allele of the x-linked gene controlling hair color;

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
