What is the scientific notation from of this numeral 541

541 = 5.41 × 10^2

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

where a is a decimal number called the mantissa and b is an integer called the exponent.

We must have 1 ≤ N < 10

Step 1. Determine the mantissa

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

541 → 5.41; N = 5.41

Step 2. Determine the exponent.

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

You moved the decimal two places to the left, so the exponent a = 2,

Step 3. Write the number in scientific notation

541 = N × 10^a = 5.41 × 10^2

the answer is the

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
