Question

Після випаровування 10 кг морської води утворилось 300г солі, яка маса води

Answer 1

Ответ:

должно быть так

300-45=255г

Answer 2

Calculation of Water Mass After Evaporation

To calculate the mass of water after the evaporation of 10 kg of seawater, we can use the fact that the remaining mass after evaporation is the initial mass minus the mass of the salt formed.

Given: - Initial mass of seawater (m1) = 10 kg - Mass of salt formed (m_salt) = 300 g

We can calculate the mass of water remaining after evaporation using the formula: Mass of water (m_water) = Initial mass - Mass of salt formed

Substituting the given values: m_water = 10 kg - 0.3 kg m_water = 9.7 kg

Therefore, after the evaporation of 10 kg of seawater, the mass of water remaining is 9.7 kg.
