Answer:
4560 torr
Explanation:
PV = K
4 x 1.5 = k
k = 6
V = k / p
V = 6 / 1
V = 6
atm to torr = 1 to 760
760 x 6 = 4560

3.8mL of 0.42 phosphoric acid is required.
Reaction
2H3PO4 + 3CaCL3 → Ca3(PO)4 + 6HCl
moles CaCl2 =0.16 mol/L x0.010 L = 0.0016 mol
moles of H3Po4
= 0.0016mol of CaCl2 x 2 mole of H3PO4/3mole of CaCl2
= 0.00106 mol
V of H3PO4 = 0.0016/0.42 = 0.0038L = 3.8mL
V of H3PO4=3.8mL

How many grams of glucose (C6H12O6) are contained in 555 mL of a 1.77 M glucose solution?
Answers
176.980176 g of glucose ([tex]C_6H_{12}O_6[/tex]) are contained in 555 mL of a 1.77 M glucose solution.
What are moles?A mole is defined as 6.02214076 × [tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
[tex]Molality = \frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}[/tex]
[tex]1.77 M = \frac{Moles \;solute}{0.555 L}[/tex]
mole solute = 0.98235 g/mol
[tex]Moles = \frac{mass}{molar \;mass}[/tex]
[tex]0.98235 g/mol = \frac{mass}{180.16 g/mol}[/tex]
mass = 176.980176 g
Hence, 176.980176 g of glucose ([tex]C_6H_{12}O_6[/tex]) are contained in 555 mL of a 1.77 M glucose solution.

A balloon is inflated to 7.0 L of volume. How many moles of gas does it contain at
STP?
0.31 moles
15 moles
3.2 moles
0.70 moles
Answers
The number of moles of gas, a balloon inflated to 7 L of volume at STP will be 0.31 moles.
What is the Molar volume ?The molar volume of a gas is the volume of one mole of a gas at STP.
At STP, one mole (6.02×10²³ particles) of any gas occupies a volume of 22.4 L
Therefore,
If 1 mole of any gas occupies 22.4 L of volume at STP
Then, X mole of gas occupies 7 L of Volume at STP
Now,
Let's equate both the above conditions ;
X / 7 L = 1 / 22.4 L
X = 1/ 22.4 L x 7 L
X = 0.31 moles
Hence, the number of moles of gas, a balloon inflated to 7 L of volume at STP will be 0.31 moles.
