Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams
Answer:
Met - Pro - Val
Explanation:
Using translation table we can see that
AUG gives Met
CCC gives Pro
GUC gives Val.
So, we have Met - Pro - Val.
Answer:
Option A, Ohio River and the Missouri River
Explanation:
The historical evidences clearly indicate that Ohio River did not exist before the last ice advances. Before Ohio and Missouri river, the major glacier drainage of the east-west direction happens in Teays River. When ice of the glaciers blocked the Teaya river valley, then the Ohio was formed.
Like Ohio, Missouri river did also not exist before Pleistocene and during that time the largest drainage in North America take place in the Hudson's Bay
Hence, option A is correct
The information as stated is false.
<h3>What is a microscope?</h3>
A microscope is a device that could be used to view the interior of a cell. It is a device that uses light to show the interior of the cell. The magnification of the microscope is what determines how much information that you could get from it.
The first compound microscope was discovered by Robert Hooke and was used extensively in the study of cells and this is how the study of microorganisms became more elaborate.
Thus, it is false to say that viewing the shape of a bacterial or archaeal cell using a microscope gives a great deal of information about the metabolism and lifestyle of the organism.
