How many grams of CaCl2 are in .48 moles// I need work shown or explanation

1. 4.57x10²³ atoms ; 2. 0.093 moles; 3. 4.5 grams ; 4. 0.434 moles , 5. 0.5 mol of Cl₂ ; 6. N₂O

Explanation:

1. 1 mol has NA atoms

0.76 mol will have (0.76 . 6.02x10²³) = 4.57x10²³ atoms

2. 6.02x10²³ particles are contained in 1 mol

5.6x10²² particles are contained in (5.6x10²²  . 1) / 6.02x10²³ = 0.093 moles

3. 1 mol of water weighs 18 g

0.25 mol . 18g/m = 4.5 grams

4. Molar mass of CaCl₂ = 110.98 g/m

Mol = Mass / molar mass → 48.2 g / 110.98 g/m = 0.434 moles

5. If the volume of Cl₂ at STP (as 1 mol of any gas) is 22.4L, and now we have the half of volume, we will have the half of moles, though. So, we have in the container 0.5 mol of Cl₂

6. 25.9% N and 74.1% O means that in 100 g of compound, we have 25.9 g of N and 74.1 g of O.

25.9 g of N / 14 g/m = 1.85 mol

74.1 g of O / 16 g/m = 4.63 mol

We divide the mol with the lowest value

4.63 mol / 1.85 mol = 2.5

1.85 mol / 1.85 mol = 1

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
