Heterogeneous means of different types. So a heterogeneous mixture is a mixture of dissimilar items. Homogeneous means of the same type so a homogeneous mixture would be a mixture of similar items.
A mixture where two or more substances are mixed together but are not chemically combined is called as an heterogeneous mixture.
In chemistry, heterogeneous mixture is a mixture of two or more different substances in the form of solution or colloids. For example, salad is an heterogeneous mixture
A heterogenous mixture is not uniform in composition and properties throughout.

Molality(m)= moles of solute divided by kilograms(kg) of
solvent
you need to find the moles of NaCl by using a conversion
factor
70g NaCl = 1mol divided by 58.44g NaCl
=1.20mol
then you need to convert 300g of water which is the solvent to
kilograms by moving the decimal over 3 units to the left which
makes .300 kg of solvent
Molality= 1.20mol divided by .300kg
Molality=4.00
