Round each number to three significant figures. 0.036549:
valina [46]

Answer:

0.0365

Explanation:

Three significant figures after the decimal include all numbers except the zeros before other numbers.

For example 0.000003431232 to three significant figures would be 0.00000343. However if the numbers are before the decimal, the zeros are included, for example 19828300 to three significant numbers would be 19800000.

Three roots of a fifth degree polynomial function f(x) are –2, 2, and 4 + i. Which statement describes the number and nature of
Daniel [21]
The two roots of this functions are the exact roots and one is an imaginary root. The -2 is the root of a negative number -16 because if you compute the -2 on its 3rd power you come up -16, the 2 is the root of 16 and the 4+i contains a imaginary number that is why it is an imaginary root

An aqueous solution containing 17.5 g of an unknown molecular compound in 100.g water was found to have a freezing point of-1.8°
Zigmanuir [339]

Answer:

The answer to your question is 178.6 g

Explanation:

Data

ΔT = 1.8 °C

mass = 17.5 g

mass of water = 100 g

Kc = 1.86

Process

1.- Calculate the molality using the following formula

    ΔTc = mKc

solve for m

    m = ΔTc/Kc

substitution

     m = 1.8/1.86

result

     m = 0.968

2.- Calculate the number of moles

    m = # of moles/kg of solvent

kg of solvent = 0.1 kg

     # of moles = m x kg of solvent

     # of moles = 0.968 x 0.1

     # of moles = 0.0968

3.- Calculate the molar mass

        x g molar mass --------------------- 1 mol

       17.5 g                  --------------------- 0.0968 moles

       x = (1 x 17.5)/0.0968

      x = 178.6 g
