How many uL are present in 250 mL of H20? (1 uL = 10^-6 Liters)​

Chemistry
1 answer:
Vanyuwa [196]3 years ago
4 0

Answer:

250000 μL

Explanation:

If         1 L = 1000 mL

Then  X L = 250 mL

X = (1 × 250) / 1000 = 0.25 L

Now we can calculate the number of microliters (μL) in 0.25 L:

if        1 μL = 10⁻⁶ L

then   X μL = 0.25 L

X = (1 × 0.25) / 10⁻⁶  =250000 μL

ratelena [41]

c. Some health risks are increased by heredity, which manifest under certain environmental conditions.

<h3>The chance of contracting some diseases can arise in particular circumstances.</h3>

The occurrence of certain diseases is influenced by certain environmental factors. Air pollution from a polluted environment increases the chance of allergic people or those with overactive immune systems acquiring respiratory conditions like asthma. A similar genetic flaw in melanin formation increases the risk of skin cancer in people who are exposed to UV rays. As a result, certain circumstances promote the development of disease.

Communities can lessen exposure to diseases and chemicals that have damaging effects on the body by focusing on environmental health. Environmental health treatments can improve everyone's quality of life, but they may be especially noticeable for people with pre-existing health conditions.

STatiana [176]

Answer:

823.7g

Explanation:

Using the formula as follows:

Q = m × c × ∆T

Where;

Q = amount of heat (J)

m = mass of substance (g)

c = specific heat capacity (J/g°C)

∆T = change in temperature (°C)

Using the information given in this question as follows:

Q = 6,400 J

m = ?

c of soil = 0.840 J/g°C

∆T = 9.25°C

Using Q = mc∆T

m = Q ÷ c∆T

m = 6,400 ÷ (0.840 × 9.25)

m = 6400 ÷ 7.77

m = 823.7g
