Answer:
Not very, because gold is too heavy to carry many bars at once.
Explanation:
Such movies are far from being accurate.
<em>A standard gold bar weighs about 12.4 kilograms, an equivalence of approximately 27 pounds or 437 ounces, in real life. Hence, a bunch of gold bars would weigh far more than what one person can just lift up, throw, or carry as if it is a bunch of cotton wool. </em>
The correct answer is, therefore, that <u>such movies are far from reality because gold is too heavy to carry many bars at once</u>.
Astronauts brought back 500 lb of rock samples from the moon. How many kilograms did they bring back? (1 kg = 2.20 lb)

I believe it is D.
Silver. It is number 47 on the periodic table meaning it has 47 protons. It’s atomic mass is 108. 47+61=108 so it is definitely silver
Answer:
191 packages of pepperoni
Explanation:
Each pizza would have 13 slices and 15 pieces of pepperoni on each one.
(because same amount of pepperoni and olives)
13 × 15 so each pizza has 195 pieces of pepperoni
138 (number of pizzas) × 195 (pieces of pepperoni)
26910 (pieces of pepperoni) / 141 (amount in each package)
= 190.85
so 191 packages
In this problem, we can formulate two equations.
First, the overall mass balance of the ointment. The mass of
30% salicylic acid ointment plus the mass of petrolatum must be 50 grams.
x + p = 50
Where x is the mass of 30% salicylic acid ointment and p is
the mass of petrolatum
Second, the component mass balance of salicylic acid:
0.3 * x = 50 * 0.05
x = 8.33 g
Therefore the mass of petrolatum to be used is:
x + p = 50
p = 50 – x
p = 50 – 8.33
p = 41.67 g
Answer:
41.7
