In a solution, a SOLUTE is the substance being dissolved.

In a solution, a SOLVENT is the substance in which something is dissolved.

For example in salt water, the salt is the solute. And the water is the solvent. Usually, which substance has a larger amount in the solution can be called a solvent. It doesn't matter if it's a gas, solid, or liquid. They can all be solute or solvents.

A few years ago, an X-ray telescope detected a source called Cygnus X-3, whose intensity changed with a period of 4.8 hours. Thi

Answer:

Explanation:

The star is revolving the black hole like earth revolves around the sun .so time period of rotation T is given by the following relation

T² = $\frac{4\pi^2\times R^3}{GM }$ , R is distance between black hole and star , M is mass of black hole

Given T = 4.8 hours

4.8² = $\frac{4\pi^2\times R^3}{GM }$

Using the same equation for earth sun system

24² = $\frac{4\pi^2\times (50R)^3}{GM_s }$ , Ms is mass of the sun and 50R is distance between the sun and the earth .

Dividing the equation

$(\frac{4.8}{24})^2$ = $\frac{M_s}{M}\times\frac{1^3}{50^3}$

$\frac{M}{M_s}$ = 2x 10⁻⁴

4. What happens during fertilization that makes the offspring unique from the original cells?

Pavlova-9 [17]

Answer:

Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

Hope it'll help!

. The artificial sweetener NutraSweet is a chemical called aspartame (C14H18N2O5). What is (a) its molecular mass (in atomic mas

loris [4]

The molecular mass, in atomic mass unit, of aspartame would be 294 amu while the mass, in kg, of an aspartame molecule would be 0.294 kg

Aspartame has the chemical formula C14H18N2O5

C = 12, H = 1, N = 14, O = 16

(a) Molecular weight = (12x14) + (1x18) + (14x2) + (16x5)

= 168 + 18 + 28 + 80

= 294 amu

(b) Mass of 1 molecule of aspartame = mole x molar mass

= 1 x 294

= 294 g

Converting 294 g to kg = 294/1000

= 0.294 kg
