Asolution has a density of 1.10g/ml. what mass of the solution has a volume of 150 ml

165 g

Explanation: solution attached:

Density is expressed as mass per unit volume

d = m/V

Derive to find mass

m= dV

= 1.10g/mL x 150 mL

= 165 g

Cancel out mL and the remaining unit is in g.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

here are some of the ways in which chemical and nuclear reactions differ.
