Answer:
3.45g/cm³
Explanation:
The density of a substance/object can be calculated by using the formula:
Density = mass/volume
Where;
Density = g/cm³
Mass = grams
Volume = cm³
According to this question, a student measured the mass and volume of an object using a triple beam balance and a graduated cylinder. The sample has a mass of 22.4 grams and a volume of 6.5cm³.
Hence, the density of the object can be calculated this;
Density = mass/volume
Density = 22.4/6.5
Density = 3.4461
To the nearest hundredth, the density of the object = 3.45g/cm³
Answer:
Choose different ways to get around your city. Walk, bike, skateboard, scooter, take public transit, as many times a week as you can. Focus especially on those short trips–for example, buy a shopping trolley and walk to the grocery store if possible.
Answer:
some of the weak-acid component of the buffer will dissociate and turn into the conjugate base (which is the weak-base component of the buffer) thus replenishing most of the protons removed.
B. population density
Explanation: took Biology
Active transport methods:
- symport - across one protein, two molecules are transported in the same time and direction
- antiport - across one protein, two molecules are transported in opposite directions, which one enters into protein and one leaves it.
I hope I helped :D
