Answer:

1:Part A.

\bold{42.2 g C_{12}H_{22}O_{11} \:in \:528 g H₂O}

Mass Percent=\bold{\frac{Mass\: of \:Solute}{Mass\: of \:Solution}×100\%}

=\frac{42.2}{528}*100\%=\bold{\underline{7.99\: or \:8\%}}

Part B.

\bold{198\:m g\: C_{6}H_{12}O_{6} \:in\:4.71 g\: H₂O}

mass of solute: 198mg

mass of solvent :4.71g=4710g

Mass Percent=\bold{\frac{Mass\: of \:Solute}{Mass\: of \:Solution}×100\%}

=\frac{198}{4710}*100\%=\bold{\underline{4.20\%}}

Part C.

\bold{8.85 g NaCl \:in \:190 g\: H₂O}

Mass Percent=\bold{\frac{Mass\: of \:Solute}{Mass\: of \:Solution}×100\%}

=\frac{8.85}{190}*100\%=\bold{\underline{4.66\%}}

Meteorologists use weather balloons to carry weather instruments high into the atmosphere. When it is first released at Earth’s
ahrayia [7]

<span>The balloons volume as it rises increases because at higher altitude external pressure is lower, so the air molecules inside the balloons tends to expand more to attain mechanical equilibrium, where the external pressure and internal pressure are equal. Unlike when the balloon is on the ground, external pressure is great so the gas molecule cannot push the walls of the balloon so it is like underinflated.</span>
