Water has a density of 1.00g/cm^3 per cubic centimeter. What is the mass of half a liter of water?
anygoal [31]

Answer:

The mass of half a liter of water is 500g, that is, 0.5kg.

Step-by-step explanation:

Density is mass divided by the volume, that is:

d = \frac{m}{v}

Here, we have to be careful. Since the density is in grams per cm³, m has to be in grams and v in cm³.

We have that:

d = 1

What is the mass of half a liter of water?

One liter is 1000 cm³.

So half a liter is 1000/2 = 500 cm³, which means that v = 500

Then

d = \frac{m}{v}

1 = \frac{m}{500}

m = 500

The mass of half a liter of water is 500g, that is, 0.5kg.

A quantity with an initial value of 7600 decays exponentially at a rate of 55% every 7 days. What is the value of the quantity a
attashe74 [19]

Answer:

1539

Step-by-step explanation:

We solve the above question using the Exponential decay formula

= A(t) = Ao(1 - r) ^t

Ao = Initial Amount invested = 7600

r = Decay rate = 55% = 0.54

t = time in weeks = 2

Hence:

A(t) = 7600(1 - 0.55)²

A(t) = 7600 × (0.45)²

A(t) = 1539

Therefore, the value of the quantity after 2 weeks is 1539
