Pepsi has a density of 1.06 g/mL. It has a mass of 370 g. What is the volume of the can of Pepsi?
Ulleksa [173]

Answer:

<h3>The answer is 320.75 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question we have

volume =  \frac{340}{1.06}  \\  = 320.7547169...

We have the final answer as

<h3>320.75 mL</h3>

Hope this helps you

Suppose a helium-3 nuclide transforms into a helium-4 nuclide by absorbing a proton and emitting a positron. Complete the nuclea
saw5 [17]

<u>Answer:</u> The nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.

<u>Explanation:</u>

Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.

Positron emission is defined as the emission process in which positron particle is emitted. In this process, a proton gets converted to neutron and an electron neutrino particle.

_Z^A\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e

The chemical equation for the reaction of He-3 with a proton follows:

_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0e

Hence, the nuclear equation for the conversion of He-3 nuclide to He-4 nuclide is given above.
