117 L. You can start by making a table to organize the information you are given. Then, you can use the formula PV/T=PV/T and plug in the numbers you have. You then solve for the missing volume. Remember that the initial pressure, temperature, and volume should be on one side of the equal sign, and the final pressure, volume, and temperature should be on the other side.
That would be mechanical because you're not changing the substance only the appearance.
I'm not completely sure but i think it's H2O. hope this helps :)
Answer:
6 atoms
Explanation:
In 6 moles of HCL (hydrochloric acid), there are 6 hydrogen atoms. Think about it this way: there is one hydrogen atom in HCL, or one hydrogen atom in one mole of HCL. Since there are 6 moles of HCL instead of one, this means there are six times as many hydrogen atoms. 6 times 1 is 6.
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
