Answer:
La concentración mencionada en el ejercicio es de:
- 2.8 x
g/mL de Na2SO4
Explanation:
Ya que el ejercicio te solicita una respuesta en g/mL, debes colocar los datos previamente en esas unidades para evitar contratiempos, quiero decir, el peso de Na2SO4 en gramos y el volumen del agua destilada en mililitros, como el agua ya está en dicha unidad, procedemos a convertir los miligramos del ejercicio a gramos, sabiendo que:
Hacemos una regla de tres simple:
Cancelamos unidades y obtenemos:
- 0.7 g
Con las unidades adecuadas, utilizamos la fórmula de concentración:
- Concentración = masa del soluto / volumen de solvente
- Concentración = 0.7 g / 250 mL
- <u>Concentración = 0.0028 g/mL de Na2SO4</u>
En notación científica sería:
- Concentración = 2.8 x g/mL de Na2SO4

Answer:
The terms health education, patient education, self-care education, school health education, and health promotion are distinguished from each other as follows. Health education is a subset or strategy within each of these but is the primary and dominant strategy in health promotion. Health education occurs through the health care providers in various settings: worksites, medical, community agencies and schools. Nurses and midwives are the most important health care providers to train people for health promotion and cancer prevention. We appreciate the importance of the "Fight against Cancer" movement in the primary health care centre and its health care providers who inform people about cancer and its symptoms, how to find lesions and early stages, and how to avoid hazardous factors. This is as process of continuous information transfer by in-service education. Primary prevention should encompass all actions aimed to reducing the occurrence of cancer. In reviewing recent advances in science and how the art of health education has been applied in practical ways within medical and other settings for prevention and public health, we can point ot the necessity for facilities like an APOCP Training Centre as a venue for scientific courses.
