To calculate moles use the eq'n
moles = mass(g) / Mr (Relative molceular Mass).
We have a mass of 135 g
The Mr is calcualted from the Periodic Table, using atomic weights/masses.
HBr =
1 x H = 1 x 1 = 1
1 x Br = 1 x 79.9 = 79.9
79.9 + 1 = 80.9
Substituting into the eq'n
moles(HBr) = 135 / 80.9
Moles = 1.66872..... ~ 1.67 moles.
The equivalent in moles is 6,03.

To find the moles of N2, we need to use the ideal gas law equation: PV = nRT. First, convert 400.0 mL to liters (0.400 L). Then convert 780 mmHg to atm (0.998 atm), and 135 degrees Celsius to Kelvin (408 K). Plug these values into the equation to solve for n, which gives you the moles of N2 in the container.
Since we know that one mole of any gas at STP is equal to 22.4 L we can multiply 135L by the following conversion: 1 mole/22.4L. When you set up the problem it looks like this: (135L)x 1 mole/22.4L =6.03 moles of oxygen gas The liters cancel out and you are left with moles as your units. Remember, if you have liters and want moles, divide by 22.4 liters; if you have moles and you want liters you multiply by 22.4 liters.

To determine how many times 3 goes into 135, you would divide 135 by 3. The result is 45, meaning that 3 goes into 135 45 times. This is because when you divide 135 by 3, you are essentially asking how many groups of 3 can fit into 135 without any remainder.
To calculate the number of atoms, we need to use Avogadro's number and the molecular weight of zinc. The molar mass of zinc is 65.38 g/mol. First, convert grams to moles: 135 g / 65.38 g/mol = 2.06 moles. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms: 2.06 moles * 6.022 x 10^23 atoms/mol = 1.24 x 10^24 atoms of zinc.
135 pounds is about 61 kilograms
135 cm = 1.35 m.
135 cm = 53.1 inches.
