The mass after 16.042 days : 1.4 g

<h3>Further explanation</h3>

Given

mass of 5.6 gram sample of I-131

time=16.042 days

Required

The mass of a sample

Solution

General formulas used in decay:  

\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{t/t\frac{1}{2} }}}

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

Half-life of I-131 = 8 days

Input the value :

\tt Nt=5.6.\dfrac{1}{2}^{16.042/8}\\\\Nt=\boxed{\bold{1.4~g}}}

If the empirical formula of a compound is C2OH4, and the molar mass is 88 g/mol, what is the molecular formula
kondor19780726 [428]

Answer:

               Molecular Formula = C₄O₂H₈

Explanation:

Molecular formula is calculated from following formula.

Molecular Formula = n(Empirical formula)

The formula for n is given as,

n = Molecular Formula Mass / Empirical Formula Mass

Molecular Formula mass = 88 g/mol

Empirical formula mass = 44

Putting values,

n = 88 / 44 = 2

Now,

Molecular Formula = 2(C₂OH₄)

Molecular Formula = C₄O₂H₈

How many grams would be in 4.45 x 10^23 molecules of N203
SVETLANKA909090 [29]

Answer:

56.24g

Explanation:

To find the mass of N2O3 in 4.45 x 10^23 molecules, it must first be converted to moles by dividing the number of molecules in N2O3 by Avagadro's number (6.02 × 10^23).

number of moles in N2O3 = 4.45 x 10^23 ÷ 6.02 × 10^23

n = 4.45/6.02 × 10^(23 - 23)

n = 0.74 × 10^0

n = 0.74moles.

Using the formula below to find the mass of N2O3;

mole = mass ÷ molar mass

Molar mass of N2O3 = 14(2) + 16(3)

= 28 + 48

= 76g/mol

mass = mole × molar mass

Mass = 0.74 × 76

Mass = 56.24g
