Answer:

<h2>mass = 50 g</h2>

Explanation:

Density of a substance can be found by using the formula

Density(\rho) =  \frac{mass}{volume}

From the question

Density = 2.5 g/mL

volume = 20 mL

To find the mass substitute the values into the above formula and solve for the mass

That's

Making mass the subject we have

mass = Density × volume

mass = 2.5 × 20

We have the final answer as

<h3>mass = 50 g</h3>

Hope this helps you

Answer:

mass=?,volume=20,density=2.5.

density=mass/volume.

which will be 2.5=mass/20

which is mass=2.5×20=50kg

Answer:

"Nitrate" is a polyatomic ion forms A neutral compound when combined with group a1 monotonic ion in a 1:1

Explanation:

Nitrate is a polyatomic ion with the molecular formula NO⁻ ₃. Organic complexes that comprise the nitrate ester as a functional group are also named nitrates. Nitrates are shared apparatuses of fertilizers and explosives. Almost all nitrate salts are soluble in water. Usually nitrates that enter the body by eating or drinking leave the body without harm. These nitrites in the blood cause changes in hemoglobin, or the molecules that help move oxygen in the body. Nitrates can make it so that less oxygen is available for the body to function properly.
