Answer:
2.57 or rounded to 1 sig digit just 3
Answer:
Step-by-step explanation:
Each atom of the gas weighs 1.67 ⋅ 10−24 grams. 6.71 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71. ... 0.67 grams, because (5.04 + 1.67) ⋅ (1023⋅ 10−24 ) = 6.71 ⋅ 10−1.
The altitude of the triangle intercepts perpendicularly
meaning that the angle EHG equals to 90 degrees
so....
12x + 30 = 90
subtract 30 from both sides
12x = 60
divide both sides by 12
x = 5
