The neutrino is the particle that cannot be accelerated in a magnetic field.

To add, a neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.

Thallium consists of 29.5%TI-203 and 70.5%TI-205. What is the relative atomic mass of thallium

Galina-37 [17]

To determine the relative atomic mass of thallium, we multiply the molar mass of the isotopes to their corresponding relative abundance. The molecular percentages should sum up to 1. In this case, we multiply 203 by 0.295 and 205 by 0.705 and add the answers of the two. The final atomic mass is 204.41 g/mol.

Answer:

are the best type of scientific investigation to demonstrate cause-and-effect relationships because they allow the investigator to actively manipulate variables and control conditions.

The sample concentration was measured at 50mg/ml. The loading concentration needs to be 10mg/ml. The final volume needs to be 25

Svet_ta [14]

Answer:

a) $V_1=5ul$

b) $v=20ul$

Explanation:

From the question we are told that:

initial Concentration $C_1=50mg/ml$

Final Concentration $C_2=10mg/ml$

Final volume needs $V_2 =25ul$

Generally the equation for Volume is mathematically given by

$C_1V_1=C_2V_2$

$V_1=\frac{C_1V_1}{C_2}$

$V_1=\frac{10*25}{50}$

$V_1=5ul$

Therefore

The volume of buffer needed is

$v=V_2-V_1\\\\v=25-5$

$v=20ul$

A series of six solutions was prepared at the given concentrations. Sample A B C D E F Concentration (mM) 50 100 150 200 300 400

ioda

Answer:

300 mM

Explanation:

In order to solve this problem we need to calculate the line of best fit for those experimental values. The absorbance values go in the Y-axis while the concentration goes in the X-axis. We can calculate the linear fit using Microsoft Excel using the LINEST function (alternatively you can write the Y data in one column and X data in another one, then use that data to create a dispersion graph and finally add the line of best fit and its formula).

The formula for the line of best fit for this set of data is:

y = 0.005 * x

So now we calculate the value of x when y is 1.50:

1.50 = 0.005 * x

x = 300 mM
