Collect the molar masses of each element contained in LiOH.

  • Lithium (Li) has a molar mass of 6.941 g/mol
  • Oxygen (O) has a mass of 15.999 g/mol
  • Hydrogen (H) has a mass of 1.008 g/mol

Together, LiOH has a molar mass of 23.948 g/mol.

Convert the given amount of LiOH from g to mol:

(67.03 g) * (1/23.948 mol/g) = 2.799 mol

Which fractions are equivalent to 10/12? Select each correct answer. ​ ​2/3​ ​5/6​ ​12/24​ ​30/36​ ​50/60​ ​60/84​
Yuri [45]

Answer:

[See Below]

Step-by-step explanation:

✦ Turn into decimals:

  • \frac{10}{12}=0.83
  • \frac{2}{3} =0.67
  • \frac{5}{6} =0.83
  • \frac{12}{24} =0.5
  • \frac{30}{36} =0.83
  • \frac{50}{60} =0.83
  • \frac{60}{84} =0.71

So \frac{10}{12} ≈ \frac{5}{6},\frac{30}{36},and,\frac{50}{60}.

-4r-11=4r+21 pls help <br>​
Masja [62]

-4r-11=4r+21

Move 4r to the other side

Sign changes from +4r to -4r

-4r-4r-11=4r-4r+21

-4r-4r-11=21

-8r-11=21

Move -11 to the other side

Sign changes from -11 to +11

-8r-11+11=21+11

-8r=21+11

-8r=32

Divide both sides by -8

-8r/-8=32/-8

Answer: r=-4

(3x – 1)(2x +9)<br> Multiplying polynomials
ad-work [718]

We can use the FOIL method to simplify.

= (3x – 1)(2x + 9)

= (3x * 2x) + (3x * 9) + (-1 * 2x) + (-1 * 9)

= 6x + 27x + (-2x) + (-9)

= 33x - 11

Hope This Helped! Good Luck!
