What is the mass of 2.35 x 10^21 moles of sodium
lora16 [44]

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

How many moles of calcium chloride are needed to react completely with 6.2 moles of silver nitrate
Harlamova29_29 [7]

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.

Cl2 + H2 + 2HCI
Cloud [144]

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
