Answer:

                      Empirical Formula  =  C₁H₄ or CH₄

Explanation:

Data Given:

                     Mass of C  =  12.0 g  

                     Mass of H  =  4 g  

Step 1: <u>Calculate Moles of each Element;</u>

                     Moles of C  =  Mass of C ÷ At.Mass of C

                     Moles of C  = 12.0 ÷ 12.0

                     Moles of C  =  1.0 mol

                     Moles of H  =  Mass of H ÷ At.Mass of H

                     Moles of H  = 4.0 ÷ 1.0

                     Moles of H  =  4.0 mol

                     Moles of O  =  %O ÷ At.Mass of O

                     Moles of O  = 53.924 ÷ 16.0

                     Moles of O  =  3.370 mol

Step 2: <u>Find out mole ratio and simplify it;</u>

                             C                                                     H                                

                            1.0                                                   4.0                              

                         1.0/1.0                                             4.0/1.0                    

                              1                                                      4                  

Hence,

              Empirical Formula  =  C₁H₄ or CH₄

How many Liters of 0.968M solution can be made if 0.581 moles of solute are added? Group of answer choices 0.600 L 60 mL 0.562 L
Rzqust [24]

Answer:

0.6L

Explanation:

The formula of molarity is molSolute/litreSolution

0.968M=\frac{0.581}{LitreSolution} \\\\LitreSolution=\frac{0.581}{0.968} \\LitreSolution=0.6L.

If 5.0 milliliters of a 0.20 M HCl solution is required to neutralize exactly10. milliliters of NaOH, what is the concentration
kirza4 [7]
NaOH+ HCl -> NaCl+ H2O
Based on the above balanced equation, we know that 1 mol HCl= 1 mol NaOH (keep it in mind; it will be used later)

We know that 0.20M HCl solution (soln)= 0.20mol HCl/1L HCl soln (this one is based on the definition of molarity).

First, we have to find the mole of HCl:
5.0mL HCl solution* (1L soln/ 1,000mL soln)* (0.20mol HCl/1L HCl soln)= 1.0*10^(-3)mol HCl.

Now that we know the mole of HCl, let's find the molarity of NaOH:
1.0*10^(-3)mol HCl* (1mol NaOH/1 mol HCl)* (1/10.mL NaOH soln)* (1,000mL NaOH soln/1L NaOH soln)= 0.10mol/L NaOH soln = 0.10M NaOH soln

Hope this would help :))
