Question

2What is the molarity of 5.00g of NaOH mixed with 550.0 mL of solution?

3How many Moles of NaCl are contained in 10L of a 2M solution?

4What mass of NaCl would be contained in the previous problem?

5Howmany moles of HCl do you have if you have 76 grams?

6Howmany liters of space does one mole of gas occupy at STP?

7How many grams of NaOH are needed to make 500mL of 2.5 M solution?

8How many mL of 6 M HCl is needed to contain 2 moles of HCl

9What are the formula's for the diatomic molecules?

10How many atoms are in one mole of Chlorine at STP?

Answer 1

2.) Atomic weights: Na=23 O=16 H=1 NaOH=40 Let the solution be called S.

5.00gNaOH/550.0mLS x 1molNaOH/40gNaOH x 1000mLS/1LS =

3.) Let the solution be called S.

10LS x 2molNaCl/1LS = 20 moles NaCl

4.) Atomic weights: Na=23 Cl=35.5 NaCl=58.5

20molNaCl x 58.5gNaCl/1molNaCl =

5.) Atomic weights: HCl=36.5

76gHCl x 1molHCl/36.5gHCl =

6.) 22.4 L

7.) Let the solution be called S

500mL x 2.5molNaOH/1LS x 40gNaOH/1molNaOH =

8.) Let the HCl solution be called S.

2molHCl x 1LS/6molHCl x 1000mLS/1LS =

9.) O2, N2, F2, Cl2, Br2, I2, At2

10.) (2) x (6.023 x 10^23) =

Answer 2

i take chem and dont know any of these lol
good luck
