Molecular mass of H2O is: 16+2*1=18
so moles of 40g of H2O is: 40/18=2.22
Answer:
V/V% = 8.2%
Explanation:
Given data:
Volume of methanol = 37.5 mL
Volume of solution = 456 mL
V/V% = ?
Solution:
V/V% = [volume of solute / volume of solution ]×100
V/V% = 37.5 mL / 456 mL × 100
V/V% = 0.08× 100
V/V% = 8.2%
Answer:
Earth's climate can be divided into three major zones: the coldest polar zone, warm and humid tropical zone, and the moderate temperate zone.
Explanation:
Answer:
<u>Gay-Lussac's law.</u>
Explanation:
According to Gay-Lussac's pressure law, it states that the pressure of a given mass of gas is <em>directly</em> proportional to the absolute temperature of the gas, the assumption that the volume is kept constant.
Hence, the trucker's tires were blown up because they were under high pressure as he drove from New Jersey to California, as a result of this intense pressure the temperature of the air in the tires began to rise and it directly affected the pressure of the gas in the tires' tubes which also increased to a point that they ended up blowing out, obeying Gay-Lussac's law.
