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

A student wants to make a 0.150 M aqueous solution of silver (I) nitrate but only has 11.27 g of AgNO3. What volume of the 0.150
Usimov [2.4K]

Answer:

442.3 mL

Explanation:

Remember that Molarity is a measure of concentration in Chemistry and it's defined as the number of moles of the substance divided by liters of the solution:

M=\frac{Moles of substance X}{Volume of the solution}

Then, you can express 11.27 g of AgNO3 as moles of AgNO3 using the molar mass of the compound:

11.27 g AgNO_{3} *\frac{1 mole AgNO_{3}}{169.87 g AgNO_{3}} = 0.06634 moles AgNO_{3}

Then you can solve for the volume of the solution:

Volume of the solution=\frac{Moles of AgNO_{3}}{M} =\frac{0.06634 mol AgNO_{3}}{0.150 M} =0.4423 L = 442.3 mL

Hope it helps!

Chlorine can bond with fluorine to form CIF. Chlorine can also bond with lithium to form LiCI Which compound will have a greater
Sergio [31]

Answer: ClF will have a greater partial charge.

Explanation:

A polar covalent bond is defined as the bond which is formed when there is a low difference of electronegativities between the atoms, thus resulting in charge difference. Example: ClF

Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms and thus there is no charge difference. Example: F_2

Ionic bond is formed when there is complete transfer of electron from a highly electropositive metal to a highly electronegative non metal. The electronegative difference between the elements is high. The charges on cation and anion neutralise each other. Example: LiCl

Thus as ClF will have greater partial charge.
