The relation between density and mass and volume is
the dose required is 2.5 tsp
each tsp contain 5mL
So dose required in mL = 2.5 X 5 = 12.5 mL
the mass will be calculated using following formula
The mass of dose in grams will be 15.38 g
Answer:
0.00370 g
Explanation:
From the given information:
To determine the amount of acid remaining using the formula:
where;
v_1 = volume of organic solvent = 20-mL
n = numbers of extractions = 4
v_2 = actual volume of water = 100-mL
k_d = distribution coefficient = 10
∴
Thus, the final amount of acid left in the water = 0.012345 * 0.30
= 0.00370 g

Science and pseudoscience differs in terms of scientific methods involved in any study. Science deals with the practices and beliefs that undergo a method of scientific study. Pseudoscience is the term associated with the ideas and beliefs that tend to be scientific in nature but they fail in their execution of following the scientific methods.
From the given options, two of them are the examples of science and not pseudoscience.
Answer:
Different liquid
Explanation:
<em>The independent variable in the investigation is the different liquid given to the plants.</em>
<u>The independent variable in an experimental investigation is the variable that is supplied by the researcher which directly affects the main variable being measured during the investigation. In other words, the independent variable is a variable that directly affects the dependent variable.</u>
In this case, the dependent variable would be growth determining factors in plants such as height, biomass, number of leaves, etc. while the independent variable would be the different types of liquid given to the plants.
