Answer:

1.0305 × 10³ kg/m³

Explanation:

A number in scientific notation has the form N × 10^a

where N is a decimal number called the <em>mantissa</em> and a is an integer called the <em>exponent.</em>

We must have 1 ≤ N < 10

Step 1. <em>Determine the mantissa </em>

Move the decimal place to the left to create a new number between 1 and 10.

1030.5 ⟶ 1.0305; N = 1.0305

===============

Step 2. <em>Determine the exponent</em>.

The exponent is the number of times you moved the decimal to get the mantissa.

You moved the decimal three places to the left, so the exponent a = 3.

===============

Step 3. <em>Write the number in scientific notation </em>

1030.5 = N × 10^a = 1.0305 × 10³

The density in scientific notation is 1.0305 × 10³ kg/m³.

The formula for density = mass/volume

So the units are gcm^3


So multiply by 1000 to get into grams - 1030500


Add units


1030500gcm^3

Suppose the data formed a line with a steeper slope. For the same change in temperature, how would the change in volume compare?
bogdanovich [222]
Substances can change state, usually when they are heated or cooled. For example, liquid water turns into steam when it is heated enough, and it turns into ice when it is cooled enough. ... The closeness, arrangement and motion of the particles in a substance change when it changes state.

Why can’t an atom lose or gain a proton
Veronika [31]

Explanation:

Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified.

Nault 25000L 250 our = 25000L 15040 8. How many grams of CaCl2 are needed to make 150.0 mL of a 0.500 M CF solution? (Note: CaCl
yuradex [85]

Answer:

You need 8,324 g of CaCl₂ yo make this solution

Explanation:

Molarity is a way to express concentration in a solution, in units of moles of solute per liter of solution.

To know the grams of CaCl₂ it is necessary to know, first, the moles of this substance with the desired volume and concentration , thus:

0,1500 L × \frac{0,500 mol}{L} = 0,075 CaCl₂ moles

Now, with the molar mass of CaCl₂ you will obtain the necessary grams, thus:

0,075 CaCl₂ moles  × \frac{110,98 g}{mol} = 8,324 g of CaCl₂

So, you need <em>8,324 g of CaCl₂</em> to make 150,0 mL of a 0,500M solution

I hope it helps!
