Answer:
1.5g
Explanation:
According to this question, the amount of copper required to obtain copper sulfide in a 4:1 is 6g. This means that the ratio of copper to sulfur in the compound (copper sulfide) is 4:1.
Hence, to calculate the amount of sulfur required for the reaction to obtain copper sulfide using the above ratio, we say:
1/4 of the amount of copper required (6g)
= 1/4 × 6
= 6/4
= 1.5g of sulfur is required for the reaction to obtain carbon sulfide.
Answer:
1. Solid
2. atom
3. faster and farther apart
4.more freely moving than a solid
5.The amount of matte in an object
Explanation:
The number of kilograms of fuel that are contained in one canister is 1.03 Kilograms
calculation
mass = density x volume
Density= 0.710 g/cm³
volume = 1.45 L
convert 1.45 l into cm³ to make the units uniform
that is 1 L= 1000 cm³
1.45 L= cm³
by cross multiplication
= (1.45 L x 1000 cm³) / 1 L = 1450 cm³
mass is therefore = 0.710g/cm³ x 1450 cm³ =1029.5 grams
convert grams to Kg
1 kg = 1000 grams
? kg =1029.5 grams
by cross multiplication
= (1 kg x 1029.5 grams) /1000 grams = 1.0295 Kg ≅1.03 kg

Molarity is one way of expressing concentration and has units of moles of solute per liter of solution. First, we need to convert the mass from grams to moles by the molar mass. Then, divide the moles with the volume of the solution.
Molarity = 4.40 g / 97.18 g/mol / .250 L
Molarity = 0.18 M
