AleksAgata [21]4 years ago
5 0

1 Gallon [Fluid] = 0.0317460317 Barrel [Fluid]

1 Gallon [Fluid] = 0.0238095238 Barrel [Oil]
1 Gallon [Dry] = 0.03809559265 Barrel [Dry]

so .1269841268 barrels if you talking about fluid

What’s the density if the mass is 40.8g and the volume is 60mL?
luda_lava [24]

Answer:

We have the final answer as

<h2>0.68 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 40.8 g

volume = 60 mL

The density is

density =  \frac{40.8}{60}  \\

We have the final answer as

<h3>0.68 g/mL</h3>

Hope this helps you

Strontium-90 is one of the products of the fission of uranium-235. This strontium isotope is radioactive, with a half-life of 28
Firlakuza [10]

Answer:

67.6 years is the time the isotope take to decay from 0.900g to 0.170g

Explanation:

The radioactive decay follows first order law:

Ln [A] = -kt + ln[A]₀

<em>Where [A] is concentration after time t,</em>

<em>k is decay constant:</em>

<em>k = ln 2 / t(1/2)</em>

<em>k = ln2 / 28.1 years</em>

<em>k = 0.02467 years⁻¹</em>

<em>[A]₀ = Initial concentration.</em>

<em />

We can replace concentration and use the mass of the isotope:

Ln [A] = -kt + ln[A]₀

Ln [0.170g] = -0.02467 years⁻¹t + ln[0.900g]

-1.667 = -0.02467 years⁻¹t

t =

<h3>67.6 years is the time the isotope take to decay from 0.900g to 0.170g</h3>
