Question

Calculate the. concentration 45g of salt with 500g of solution​

Answer 1

Salt molecular formula is NaCl

Molecular Mass = 23 + 35.5 = 58.5

Moles = $\frac{GivenMass}{MolecularMass}$ = $\frac{45}{58.5}$ ≅ 0.8

Here by the term 'concentration' we mean finding Molality.

So, Molality = $\frac{Moles*1000}{Weight(Grams)}$ = $\frac{0.8*1000}{500}$ = $1.6$

Hence:

$\huge\boxed{Concentration=1.6}$

Answer 2

Answer:

Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
