Answer:
A. Polar regions receive less solar energy and heat per unit area than tropical regions.
Explanation:
The sun is lower in the sky the farther away from the equator you go (at higher latitudes), so the solar energy is less direct. Climate in areas with less direct solar input tends to be generally cooler.
Answer:
the sucrose mass is 264.g
Explanation:
The computation of the sucrose mass is shown below;
The Molar mass of is 342.3 g/mol
And, the molar mass of is 18g/mol
The mass of be Y
Now
The moles of is
= Mass of ÷ molar mass of
= Y ÷ 342.3 mol
And,
The moles of is
= Mass of ÷ molar mass of
= 100.0 ÷ 18
= 5.56mol
Now
The molar fraction of is
= Moles of ÷ (moles of + moles of ) = 0.124
= (Y ÷ 342.3) ÷ [(Y ÷ 342.3) + 5.56] = 0.124
Y ÷ 342.3 = 0.124 × [(Y ÷ 342.3 + 5.56]
Y = 0.124 × Y + (0.124 × 5.56 × 342.3)
Y = 269.4 g
hence, the sucrose mass is 264.g
