Question :—

1.Calculate the mass percent of salt in salt water if 1 gram of salt is dissolved into 99 grams of water. Show the steps in your calculation.

Answer :—

Mas of common salt (solute)=1 g

Mas of common salt (solute)=1 Mass of water (soluted) =99 g

Mas of common salt (solute)=1 gMass of water (soluted) =99 gmass of solution =1+99 = 100

gconcentration of solution= mass of solution (M mass of solute) ×100

=> 1% [/tex]Hence, the concentration of the solution is 1%

a. they are both space stations

happy to

pls mark as brainliest.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
