Answer:
~.1058 Moles
Explanation:
The formula for this question is the following.
1 mole of a compound/molar mass of the compound.
First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.
1 mole of H2O/ 17.01 g/mol H2O
We now know that in 1 mole of H20 there is 17.01 g.
Take 1.8g and divide it by 17.01, you get your answer.
Zinc chloride and aluminum
Answer:
an accelerant was used because maybe some was spilt and therefore leaving a smell and evidence
Answer:
T₂ = 242 K
Explanation:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Given data:
Initial volume = 125 mL
Initial pressure = 1.77 atm
Initial temperature = 213 °C (213 +273 = 486 K)
Final volume = 136 mL
Final pressure = 0.810 atm
Final temperature = ?
Solution:
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂T₁ / P₁V₁
T₂ = 0.810 atm × 136 mL × 486 K / 1.77 atm× 125 mL
T₂ = 53537.76 atm .mL. K / 221.25 atm . mL
T₂ = 242 K
