Answer:
5.41 x 10²² g
Explanation:
Data Given:
no. of moles of sodium = 2.35 x 10²¹ moles
mass of sodium = ?
Solution:
Formula used
no. of moles = mass in grams / molar mass
To find mass rearrange the above equation:
mass in grams = no. of moles x molar mass. . . . . . (1)
- molar mass of Sodium (Na) = 23 g/mol
Put values in equation 1
mass in grams = 2.35 x 10²¹ moles x 23 g/mol
mass in grams = 5.41 x 10²² g
So,
mass of Sodium (Na) = 5.41 x 10²² g
Answer:
3.1 mol
Step-by-step explanation:
The balanced equation is
CaCl₂ + 2AgNO₃ ⟶ Ca(NO₃)₂ + 2AgCl
You want to convert moles of AgNO₃ to moles of CaCl₂.
The molar ratio is 2 mol AgNO₃:1 mol CaCl₂
Moles of CaCl₂ = 6.2 mol AgNO₃ × (1 mol CaCl₂/2 mol AgNO₃)
Moles of CaCl₂ = 3.1 mol CaCl₂
The reaction will require 3.1 mol of CaCl₂.
Answer:
1 and 2
Explanation:
The given equation is:
Cl₂ + H₂ → 2HCl
A coefficient is the variable or number before a chemical specie.
In this reaction Cl₂ and H₂ are the reactants;
The coefficient of Cl₂ is 1,
H₂ is 1,
HCl is 2
The subscript is the number to the lower power after a chemical specie is denoted.
For Cl₂, it is 2
