It's imperative to have standard units for measuring quantities with the goal that the quantities are uniform.

Further Explanation:

measuring quantities:

In a physical setting an estimation instrument might be checked to estimating substances of a particular physical amount. In such a setting the particular physical amount is known as a deliberate amount. The synonymous thought "noticeable" regularly is utilized with regards to quantum mechanics.  

Standard units:  

which means of standard unit alludes to a unit of specific arrangement of units of estimation called the standard framework (versus the decimal measuring standard). The standard framework incorporates the standard units of the foot, the pound (mass), and the gallon.  

Standard units are utilized in estimation:  

A standard unit of estimation is a quantifiable language that enables everybody to comprehend the relationship of the article with the estimation. It is communicated in inches, feet, and pounds, in the United States, and centimeters, meters, and kilograms in the decimal standard for measuring.  

Techniques for Measurement:  

Direct Method of Measurement, In this technique for estimation, the obscure amount is straightforwardly contrasted and the standard amount. The consequence of the amount is communicated in number. It is the most widely recognized strategy for estimating the physical amounts like length, temperature, weight, and so on.

Subject: chemistry

Carbon-14 has a half-life of 5,700 years.
Maksim231197 [3]

Answer:

3.106\ \text{g}

Explanation:

t_{1/2} = Half-life of carbon = 5700 years

t = Time at which the remaining mass is to be found = 10400 years

m_0 = Initial mass of carbon = 11 g

Decay constant is given by

\lambda=\dfrac{\ln2}{t_{1/2}}

Amount of mass remaining is given by

m=m_0e^{-\lambda t}\\\Rightarrow m=m_0e^{-\dfrac{\ln2}{t_{1/2}} t}\\\Rightarrow m=11e^{-\dfrac{\ln 2}{5700}\times 10400}\\\Rightarrow m=3.106\ \text{g}

The amount of the substance that remains after 10400 years is 3.106\ \text{g}.

If a 67.3G rock is dissolved in 2.00L of acid, what is the molar concentration of gold in the acid solution
brilliants [131]

Answer:

[Au] = 0.171 M

Explanation:

For this question, we assume the rock is 100 % gold.

First of all, we determine the moles of gold

67.3 g . 1mol/ 196.97g = 0.342 moles

Molar concentration is defined as the moles of solute, contained in 1L of solution.

Our solution volume is 2L.

M = 0.342 mol / 2L = 0.171

Molar concentration, also called molarity of solution is the most typical unit of concentration.
